'''WASP-121''' is a [[apparent magnitude|magnitude]] 10.4 [[star]] located approximately 850 [[light-year]]s away in the [[constellation]] [[Puppis]].<ref name="Constellation" /> WASP-121 has a [[mass]] and [[radius]] similar to the [[Sun]]. Its planet [[WASP-121b]] orbits around WASP-121 in about 1.27 days.<ref name="EP-2015" /> WASP-121b is the first exoplanet found to contain [[water]] in an extrasolar planetary [[stratosphere]] (i.e., an [[atmosphere|atmospheric layer]] in which temperatures increase as the altitude increases).<ref name="NASA-20170802" /><ref name="NAT-20170802" />

It hosts one known [[exoplanet]].


The star, although metal-rich in terms of overall contents of heavy elements, is depleted of carbon. The carbon to oxygen molar ratio of 0.23{{±|0.05}} for WASP-121 is well below the solar ratio of 0.55.<ref>{{citation|arxiv=2207.13662|year=2022|title=Chemical Abundances for 25 JWST Exoplanet Host Stars with KeckSpec|last1=Polanski |first1=Alex S. |last2=Crossfield |first2=Ian J.

The designation ''WASP-121'' indicates that this was the 121st star found to have a planet by the [[Wide Angle Search for Planets]].

In August 2022, this planetary system was included among 20 systems to be named by the third [[NameExoWorlds]] project.<ref>{{cite web |url=https://www.nameexoworlds.iau.org/2022exoworlds |title=List of ExoWorlds 2022 |date=8 August 2022 |website=nameexoworlds.iau.org |publisher=[[International Astronomical Union|IAU]] |access-date=27 August 2022}}</ref> The approved names, proposed by a team from [[Bahrain]], were announced in June 2023. WASP-121 is named '''Dilmun''' after the [[Dilmun|ancient civilization]], and its planet is named '''Tylos''' after the [[Tylos|ancient Greek name]] for Bahrain.<ref name="NEW2022"/>

WASP-121, also known as CD-38 3220 and formally named Dilmun,[7] is a magnitude 10.4 star located approximately 858 light-years (263 parsecs) away in the constellation Puppis.[1] WASP-121 has a mass and radius similar to the Sun's. It hosts one known exoplanet.

The star, although metal-rich in terms of overall contents of heavy elements, is depleted of carbon. The carbon to oxygen molar ratio of 0.23±0.05 for WASP-121 is well below the solar ratio of 0.55.[8]

Nomenclature

[edit]

The designation WASP-121 indicates that this was the 121st star found to have a planet by the Wide Angle Search for Planets.

In August 2022, this planetary system was included among 20 systems to be named by the third NameExoWorlds project.[9] The approved names, proposed by a team from Bahrain, were announced in June 2023. WASP-121 is named Dilmun after the ancient civilization, and its planet is named Tylos after the ancient Greek name for Bahrain.[10]

Planetary system

[edit]

In 2015, the exoplanet WASP-121b was discovered orbiting WASP-121 by the transit method.[3][11] WASP-121b is a hot Jupiter with a mass about 1.18 times that of Jupiter and a radius about 1.81 times that of Jupiter.[4][12] The exoplanet orbits WASP-121, its host star, every 1.27 days.[4][12] Hot water molecules have been found in the stratosphere of WASP-121b (i.e., the atmospheric layer in which temperatures increase as the altitude increases).[3][12][13][14]
